Prostheses, Cardiac Ventricle, Percutaneously Powered

Definition : Cardiac-ventricle prostheses that include an implantable pumping mechanism with a percutaneous connection to an external power source (either electrical or pneumatic) that supplies the driving power. These devices typically consist of an implantable pump that works as an artificial ventricle by pushing the blood from the inlet valve to the outlet valve and then through the circulatory system and an electrical or pneumatic external power system that is connected to the implanted pump through electrical wires or pneumatic drive lines that enter the left part of the patient's chest. Both pulsatile-flow and continuous-flow pump systems are available. Percutaneously powered heart prostheses include a battery and/or a pneumatic console that is permanently attached to the patient for power supply and control of the pumping rate and pressure of the implanted prosthesis. These prostheses are used mainly as a temporary bridge to transplantation, but some battery powered units may be capable of long-term use.

MicroMed Technology Inc

In 1984, Dr. Michael DeBakey and Dr. George Noon performed heart transplant surgery on NASA-Johnson Space Center (JSC) Engineer David Saucier, following a severe heart attack. Six months later, Saucier returned to JSC with the desire to apply spacecraft technology to help people with diseased hearts. As early as 1987, informal meetings began with NASA engineers and Drs. DeBakey and Noon to discuss the design of a low-cost, low-power, implantable ventricular assist device (VAD). Dr. DeBakey instructed the engineers to design a pump that can drain a swimming pool full of water balloons without breaking a single one.

World Heart Inc

WorldHeart is developing the MiFlow™ VAD: a minimally invasive, magnetically levitated miniature rotary blood pump designed to address significant issues of current VADs – including stroke, bleeding, device failures and invasiveness of implantation. VADs are mechanical devices that are surgically implanted to support a patient's own heart by pumping a portion of the cardiac output.
